T-Cell Therapy

Multiple sclerosis and Tcelna™

Tcelna™ is a novel T-cell immunotherapy in Phase IIb clinical development for the resulttreatment of patients with secondary progressive MS (SPMS).  It is also positioned to enter Phase III clinical development for the treatment of patients with relapsing remitting MS (RRMS), subject to the availability of sufficient resources.  Tcelna is a personalized therapy that is specifically tailored to each patient’s disease profile.  Tcelna is manufactured using ImmPath™, our proprietary method for the production of a person’s own T-cells attackingpatient-specific T-cell immunotherapy, which encompasses the myelin sheath that coatscollection of blood from the nerveMS patient, isolation of peripheral blood mononuclear cells, generation of the central nervous system (CNS). Tovaxin consistsan autologous pool of attenuated patient-specific myelin reactivemyelin-reactive T-cells (MRTCs) raised against selected peptides from one or more of the primary proteins on the surface of the myelin sheath (myelin basic protein (MBP), proteolipid protein (PLP) and myelin oligodendrocyte glycoprotein (MOG)). Patient-specific MRTCs are and proteolipid protein (PLP), and the return of these expanded, in culture with specific peptides identified by our proprietary test of the patient’s peripheral blood. The cells are then attenuated by gamma irradiation, and returnedirradiated T-cells back to the patient as a subcutaneous injection. Although further testing is necessary, results from our initial human trials appear to indicate that thesepatient.  These attenuated T-cells cause anare reintroduced into the patient via subcutaneous injection to trigger a therapeutic immune response directed at the autoreactive T-cellssystem response.

Initiation of Phase IIb Clinical Study in the patient’s body, resulting inPatients with SPMS
We recently initiated a reduction in the level of harmful T-cells. In 2008, we completed an FDA cleared Phase IIb clinical trial of Tovaxin which

enrolled 150-patients.Tcelna in patients with SPMS.  The trial was entitled, is entitled:  A Multicenter, Randomized,Phase II Double-Blind, Placebo-ControlledPlacebo Controlled Multi-Center Study to Evaluate the Efficacy and Safety of Subcutaneous TovaxinTcelna in Subjects with Clinically Isolated SyndromeSecondary Progressive Multiple Sclerosis and has been named the “Abili-T” trial.  The newly-initiated Abili-T trial is a double-blind, 1:1 randomized, placebo-controlled study in SPMS patients who demonstrate evidence of disease progression without associated relapses.  The trial is expected to enroll 180 patients at approximately 30 leading clinical sites in the U.S. and Canada and is expected to take approximately three years to complete.  According to the study protocol, patients will receive two annual courses of Tcelna treatment consisting of five subcutaneous injections per year at weeks 0, 4, 8, 12 and 24.  The primary efficacy endpoint of the trial is the percentage of brain volume change (atrophy) at 24 months.  Study investigators will also measure several important secondary outcomes commonly associated with MS including disease progression as measured by Expanded Disability Status Scale (EDSS), annualized relapse rate (ARR) and changes in disability as measured by EDSS and the Multiple Sclerosis Functional Composite (MSFC).  The Abili-T clinical trial is expected to enroll over a 12-month period and the resulting top-line data is expected by the end of 2015.

Tcelna is the first ever personalized T-cell therapy for MS patients and has received Fast Track designation from the FDA in SPMS.  The FDA’s Fast Track program is designed to facilitate the development and expedite the review of drugs intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical need.
The costs of the study, as well as the ongoing expenses of our operations through the expected completion date of such study, are estimated at approximately $35 million.  Our existing resources are not adequate to permit us to proceed materially beyond the initiation of the study (i.e., the dosing of the first patients) or to complete such study or any significant portion of it.  We will need to secure significant additional resources to continue and complete the trial and support our operations during the pendency of the trial.
Given our need for substantial amounts of capital to continue and complete the Phase IIb clinical study in North America of Tcelna in SPMS, we intend to continue to explore potential opportunities and alternatives to obtain the additional resources that will be necessary to continue and complete the Phase IIb study and to support ongoing operations during the pendency of such study.  In addition to one or more additional financings, these opportunities and alternatives may include a partnering arrangement with a large biotech or pharmaceutical company.  There can be no assurance that any such financings or partnering arrangement can be consummated on acceptable terms, if at all.
SPMS Overview
SPMS is characterized by a steady accrual of irreversible disability, despite, in some cases, reversible relapses, remissions or clinical plateaus.  Older age at onset of MS diagnosis is the strongest predictor of conversion to SPMS.  Males have a shorter time to conversion to SPMS compared with females.  Available immunomodulating and immunosuppressive therapies used for RRMS have not been effective in SPMS.  In clinical trials, these therapies have demonstrated anti-inflammatory properties as measured by the reduction in number and volume of contrast-enhancing or acutely inflammatory central nervous system (CNS) lesions most commonly seen in patients with RRMS.  The typical SPMS patient, however, has little or no radiographic evidence of acute inflammation.  It is commonly observed that contrast-enhancing CNS lesions are uncommon among these patients, despite a clearly deteriorating neurologic course.  The lack of effect of conventional MS therapeutics in SPMS suggests that the cerebral deterioration characterizing progressive disease may be driven by factors other than acute inflammation.  For instance, the immunopathology of SPMS is more consistent with a transition to a chronic T-cell dependent inflammatory type, which may encompass the innate immune response and persistent activation of microglia cells.  Radiographic features that stand out among patients with SPMS include significantly more atrophy of gray matter compared with RRMS patients.  Of note, long-term disability in MS in general appears more closely correlated to gray matter atrophy than to white matter inflammation.  Such atrophy may be suggestive of progressive clinical disability.  Both clinically and radiographically, SPMS represents a disease process with certain features distinct from those of RRMS, and one with extremely limited treatment options.
2

Current Treatment Options for SPMS
Only one product, mitoxantrone, is currently approved for the indication of SPMS.  However, as of 2005, this drug carries a black box warning, due to significant risks of decreased systolic function, heart failure, and leukemia.  The American Academy of Neurology has issued a report indicating that these risks are even higher than suggested in the original report leading to the black box warning.  Hence, a safe and effective treatment for SPMS remains a significant unmet medical need.
Tcelna Clinical Overview in SPMS
In multiple previously conducted clinical trials for the treatment of patients with MS (which have been weighted significantly toward patients with Relapsing Remitting Multiple Sclerosis. (TovaxinMS (RRMS)), Tcelna has demonstrated one of the safest side effect profiles for any marketed or development-stage MS therapy, as well as encouraging efficacy signals.  A total of 142 MS patients have received Tcelna in previously conducted trials for RRMS and SPMS.  The therapy has been well tolerated in all subjects and has demonstrated an excellent overall safety profile.  The most common side effect is mild to moderate irritation at the site of injection, which is typically resolved in 24 hours.  Tcelna has been administered to a total of 36 subjects with SPMS across three clinical studies.  Based on preliminary data suggesting stabilized or improved disability among SPMS subjects receiving Tcelna, Opexa believes that further development of this product in SPMS is warranted.
Summary of TERMS Phase IIb Clinical Trial Data in RRMS
Tovaxin for Early Relapsing-remitting MS, “TERMS”).

Relapsing Multiple Sclerosis (TERMS) was a Phase IIb clinical study of Tcelna in RRMS patients completed in 2008.  Although the study did not show statistical significance in its primary endpoint (the cumulative number of gadolinium-enhanced brain lesions using MRI scans summed at various points in the study), the study showed compelling evidence of efficacy in various clinical and other MRI endpoints.

The TERMS study was a Phase IIb multi-center, randomized, double blind, placebo-controlled trial in 150 patients with Relapsing-Remitting Multiple Sclerosis (RRMS)RRMS or high risk Clinically Isolated Syndrome (CIS). The study involved 2:1 randomization with 100 patients receiving Tovaxin and 50 receiving placebo. According to the study protocol, patientsSyndrome.  Patients received a total of five subcutaneous injections at weeks 0, 4, 8, 12 and 24.  Top-line dataKey results from the TERMS trial is as follows:

included:

Annualized relapse rate (ARR) for Tovaxin-treated patients was 0.214 as compared to 0.339 for placebo-treated patients, which represented a 37% decrease in ARR for Tovaxin as compared to placebo in the general population.

In the modified intent to treat patient population (n=142), the ARR for Tcelna-treated patients was 0.214 as compared to 0.339 for placebo-treated patients, which represented a 37% decrease in ARR for Tcelna as compared to placebo in the general population;

For

In a prospective group of patients who hadwith more active disease as indicated by an ARR > (ARR>1, in the year prior to the study, Tovaxinn=50), Tcelna demonstrated a 55% reduction in ARR as compared to placebo;placebo, and an 87%a 73% reduction in relapse rate was observed in TovaxinTcelna patients in this population compared to placebo during the 24 week24-week period following the administration of the full course of treatment; and
In a retrospective analysis in patients naïve to previous disease modifying treatment (p=0.039).

Patients(i.e., patients who had an ARR>1 at entry demonstrated a statistically significant improvement in disability score as measured bynot previously used any drugs other than steroids to treat their disease), the Expanded Disability Status Scale (EDSS) (p =0.045) forresults showed that patients, when treated with Tovaxin as compared to those receiving placebo. The EDSS score isTcelna, had a measure of disability ranging from 0-10. In addition 28.1% of the Tovaxin patients showed an improvement in EDSS of at least one point as compared to 5.6% in the placebo group.

Patients who had an ARR>1 at entry and were treated with Tovaxin experienced an 88%64% reduction in brain atrophy and a 59% reduction in absolute T-2 lesion volume as compared to placebo.

ARR versus placebo (p=0.046, n=70).

Tovaxin was safe and well tolerated with no serious adverse events related

We remain committed to Tovaxin treatment. The most common adverse event was injection site irritation.

Further analysisfurther advancing Tcelna in RRMS at a later date assuming the availability of the TERMS clinical study of 150 patients with RRMS evaluated those patients withsufficient resources.  For Opexa, however, progressive MS is an annualized relapse rate of one or greater than or equal to one at study entry (ARR³1). More than 83% of the Tovaxin-treated group (n=85) remained relapse free at one year and the annualized relapse rate after treatment decreased to 0.20,area which we believe represents a 42% reduction compared to placebo. The results of this expanded analysis confirm those found in the previously-reported per-protocol analysis of patients in the TERMS study with ARR>1. This post-hoc analysis which represents 86% of the total patient population in the TERMS study was conducted to evaluate Tovaxin treatment among study patients with the same baseline disease activity that is being targeted for inclusion in the forthcoming Phase IIb study. Along with a marked reduction in relapses, 73% of the Tovaxin-treated patients with ARR³1 showed stabilization or improvement in MS disability, including 16.5% with a sustained improvement in the Expanded Disability Status Scale (EDSS) of at least one full point. On MRI, the Tovaxin-treated group also demonstrated a reduction in brain atrophy and fewer inflammatory brain lesions that progressed to “black holes,” as compared to the placebo-treated group. Treatment with Tovaxin was well tolerated, with no serious adverse events reported in any Tovaxin-treated patient.

Tovaxin is a personalized T-cell vaccine based on a patient’s individual immunologic profile. Detailed immunology data analysis from the TERMS trial indicate that Tovaxin can successfully induce changes in T-cell reactivity to all three targeted myelin antigens implicated in the autoimmune attacks causing neurologic damage in MS. These changes appear epitope-specific, are sustained for 6 months or more, and match each patient’s Tovaxin formulation. Tovaxin is not broadly immunosuppressive, an important feature of its favorable safety profile.

higher unmet medical need.

Other Opportunities

Our proprietary T-cell technology has enabled us to develop intellectual property and a comprehensive sample database that may enable discovery of novel biomarkers and other relevant peptides to be used to treat MS patients.

Stem Cell TherapyWe have developed (and, in part, in-licensed from the University of Chicago) a proprietary adult stem cell technology to produce monocyte-derived stem cells (MDSC) from blood.  These MDSC can be derived from a patient’s monocytes, expanded ex vivo

In August 2009, we entered into an exclusive agreement with Novartis, and then administered to the same patient.  Our initial focus for this technology is the further development of our novel stem cell technology. This technology, which has generated preliminary data showing the potential to generate monocyte derived islet cells from peripheral blood mononuclear cells, was in early preclinical development at Opexa. Under the terms of the agreement, Novartis acquired thethis monocyte-derived stem cell technology from us and Novartis will have full responsibilityas a platform for funding and carrying out all research,the in vitro generation of highly specialized cells for potential application in autologous cell therapy for patients with diabetes mellitus.  The diabetes program is in an early (pre-clinical) development and commercialization activities. To date we have received $3.5 million from Novartis of which $3 million was attributable to an upfront cash payment and $0.5 million resulted from the completion of the first of two technology transfer milestones. We will receive an additional $0.5 million technology transfer fee upon the completion of the second technology transfer milestone which is anticipated to occur within the next six months. We are also eligible to receive certain clinical and commercial milestone payments as well as royalty payments from the sale of any products resulting from the use of the technology and we retain an option on certain manufacturing rights.

DESCRIPTION OF DEBT SECURITIES

The following is a summary of the general terms of the debt securities.  We will file a prospectus supplement that may contain additional terms when we issue debt securities.  The terms presented here, together with the terms in a related prospectus supplement, will be a description of the material terms of the debt securities.  You should also read the indenture under which the debt securities are to be issued.  We have filed a form of indenture governing different types of debt securities with the SEC as an exhibit to the registration statement of which this prospectus is a part.  All capitalized terms have the meanings specified in the indenture.

We may issue, from time to time, debt securities, in one or more series.  The debt securities we offer will be issued under an indenture between us and the trustee named in the indenture.  These debt securities that we may issue include senior debt securities, subordinated debt securities, convertible debt securities and exchangeable debt securities.  The following is a summary of the material provisions of the indenture filed as an exhibit to the registration statement of which this prospectus is a part.  For each series of debt securities, the applicable prospectus supplement for the series may change and supplement the summary below.

General Terms of the Indenture

The indenture does not limit the amount of debt securities that we may issue.  It provides that we may issue debt securities up to the principal amount that we may authorize and they may be in any currency or currency unit that we may designate.  Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.  For each series of debt securities, any restrictive covenants for those debt securities will be described in the applicable prospectus supplement for those debt securities.

Consolidation, Merger or Sale

The terms of the indenture prevent us from (i) consolidating

We cannot consolidate or mergingmerge with or into, or transferringtransfer or leasinglease all or substantially all of our assets to, any person, unless the successor corporation or person to which our assets are transferred or leased is organized under the laws of the United States, any state of the United States or the District of Columbia and it expressly assumes our obligations under the debt securities and the indenture or (ii) completingindenture.  In addition, we cannot complete such a transaction unless immediately after completing the transaction, no event of default under the indenture, and no event that, after notice or lapse of time or both, would become an event of default under the indenture, has occurred and is continuing.  When the person to whom our assets are transferred or leased has assumed our obligations under the debt securities and the indenture, we will be discharged from all our obligations under the debt securities and the indenture except in limited circumstances.

This covenant would not apply to any recapitalization transaction, a change of control affecting us or a highly leveraged transaction, unless the transaction or change of control were structured to include a merger or consolidation or transfer or lease of all or substantially all of our assets.

Events of Default

The indenture provides that the following will be “events of default” with respect to any series of debt securities:

failure to pay interest for 30 days after the date payment is due and payable;

failure to pay principal or premium, if any, on any debt security when due, either at maturity, upon any redemption, by declaration or otherwise and, in the case of technical or administrative difficulties, only if such default persists for a period of more than three business days;

failure to pay interest for 30 days after the date payment is due and payable;
failure to pay principal or premium, if any, on any debt security when due, either at maturity, upon any redemption, by declaration or otherwise and, in the case of technical or administrative difficulties, only if such default persists for a period of more than three business days;
failure to make sinking fund payments when due and continuance of such default for a period of 30 days;
failure to perform other covenants for 60 days after notice that performance was required;
events in bankruptcy, insolvency or reorganization relating to us; or
any other event of default provided in the applicable officer’s certificate, resolution of our board of directors or the supplemental indenture under which we issue a series of debt securities.

failure to make sinking fund payments when due and continuance of such default for a period of 30 days;

failure to perform other covenants for 60 days after notice that performance was required;

events in bankruptcy, insolvency or reorganization relating to us; or

any other event of default provided in the applicable officer’s certificate, resolution of our board of directors or the supplemental indenture under which we issue a series of debt securities.

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under the indenture.  For each series of debt securities, any modifications to the above events of default will be described in the applicable prospectus supplement for those debt securities.

The indenture provides that if an event of default specified in the first, second, third, fourth or sixth bullets above occurs and is continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may declare the principal amount of all those debt securities (or, in the case of discount securities or indexed securities, that portion of the principal amount as may be specified in the terms of that series) to be due and payable immediately.  If an event of default specified in the fifth bullet above occurs and is continuing, then the principal amount of all those debt securities (or, in the case of discount securities or indexed securities, that portion of the principal amount as may be specified in the terms of that series) will be due and

payable immediately, without any declaration or other act on the part of the trustee or any holder.  In certain cases, holders of a majority in principal amount of the outstanding debt securities of any series may, on behalf of holders of all those debt securities, rescind and annul a declaration of acceleration.

The indenture imposes limitations on suits brought by holders of debt securities against us.  Except for actions for payment of overdue principal or interest, no holder of debt securities of any series may institute any action against us under the indenture unless:

the holder has previously given to the trustee written notice of default and continuance of such default;

the holders of at least 25% in principal amount of the outstanding debt securities of the affected series have requested that the trustee institute the action;

the requesting holders have offered the trustee indemnity for the reasonable expenses and liabilities that may be incurred by bringing the action;

the trustee has not instituted the action within 60 days of the request and offer of indemnity; and

7

the trustee has not received inconsistent direction by the holders of a majority in principal amount of the outstanding debt securities of the affected series.


the holder has previously given to the trustee written notice of default and continuance of such default;
the holders of at least 25% in principal amount of the outstanding debt securities of the affected series have requested that the trustee institute the action;
the requesting holders have offered the trustee indemnity for the reasonable expenses and liabilities that may be incurred by bringing the action;
the trustee has not instituted the action within 60 days of the request and offer of indemnity; and
the trustee has not received inconsistent direction by the holders of a majority in principal amount of the outstanding debt securities of the affected series.
We will be required to file annually with the trustee a certificate, signed by one of our officers, stating whether or not the officer knows of any default by us in the performance, observance or fulfillment of any condition or covenant of the indenture.

Discharge, Defeasance and Covenant Defeasance

We can discharge or decrease our obligations under the indenture as stated below.

We may discharge obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that have either become due and payable or are by their terms to become due and payable, or are scheduled for redemption, within one year.  We may effect a discharge by irrevocably depositing with the trustee cash or government obligations denominated in the currency of the debt securities, as trust funds, in an amount certified to be enough to pay when due, whether at maturity, upon redemption or otherwise, the principal of, and any premium and interest on, the debt securities and any mandatory sinking fund payments.

Unless otherwise provided in the applicable prospectus supplement, we may also discharge any and all of our obligations to holders of any series of debt securities at any time, which we refer to as defeasance.  We may also be released from the obligations imposed by any covenants of any outstanding series of debt securities and provisions of the indenture, and we may omit to comply with those covenants without creating an event of default under the trust declaration, which we refer to as covenant defeasance.  We may effect defeasance and covenant defeasance only if, among other things:

we irrevocably deposit with the trustee cash or government obligations denominated in the currency of the debt securities, as trust funds, in an amount certified to be enough to pay at maturity, or upon redemption, the principal (including any mandatory sinking fund payments) of, and any premium and interest on, all outstanding debt securities of the series; and

we deliver to the trustee an opinion of counsel from a nationally recognized law firm to the effect that the holders of the series of debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance or covenant defeasance and that defeasance or covenant defeasance will not otherwise alter the holders’ U.S. federal income tax treatment of principal, and any premium and interest payments on, the series of debt securities.

we irrevocably deposit with the trustee cash or government obligations denominated in the currency of the debt securities, as trust funds, in an amount certified to be enough to pay at maturity, or upon redemption, the principal (including any mandatory sinking fund payments) of, and any premium and interest on, all outstanding debt securities of the series; and
we deliver to the trustee an opinion of counsel from a nationally recognized law firm to the effect that the holders of the series of debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance or covenant defeasance and that defeasance or covenant defeasance will not otherwise alter the holders’ U.S. federal income tax treatment of principal, and any premium and interest payments on, the series of debt securities.

In the case of a defeasance by us, the opinion we deliver must be based on a ruling of the Internal Revenue Service issued, or a change in U.S. federal income tax law occurring, after the date of the indenture, since such a result would not occur under the U.S. federal income tax laws in effect on that date.

Although we may discharge or decrease our obligations under the indenture as described in the two preceding paragraphs, we may not avoid, among other things, our duty to register the transfer or exchange of any series of debt securities, to replace any temporary, mutilated, destroyed, lost or stolen series of debt securities or to maintain an office or agency in respect of any series of debt securities.

The indenture provides that we and the trustee may enter into supplemental indentures without the consent of the holders of debt securities to, among other things:

make any other provisions with respect to matters or questions arising under the indenture that will not be inconsistent with any provision of the indenture as long as the new provisions do not adversely affect the interests of the holders of any outstanding debt securities of any series created prior to the modification.

make any other provisions with respect to matters or questions arising under the indenture that will not be inconsistent with any provision of the indenture as long as the new provisions do not adversely affect the interests of the holders of any outstanding debt securities of any series created prior to the modification.

The indenture also provides that we and the trustee may, with the consent of the holders of not less than a majority in aggregate principal amount of debt securities of each series of debt securities affected by such supplemental indenture then outstanding, add any provisions to, or change in any manner, eliminate or modify in any way the provisions of, the indenture or any supplemental indenture or modify in any manner the rights of the holders of the debt securities.  We and the trustee may not, however, without the consent of the holder of each outstanding debt security affected thereby:

reduce the principal amount or premium, if any;

The indenture provides that the holders of not less than a majority in aggregate principal amount of the then outstanding debt securities of any series, by notice to the relevant trustee, may on behalf of the holders of the debt securities of that series waive any default and its consequences under the indenture except:

a default in the payment of, any premium and any interest on, or principal of, any such debt security held by a nonconsenting holder; or

a default in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security of each series affected.

a default in the payment of, any premium and any interest on, or principal of, any such debt security held by a nonconsenting holder; or
a default in respect of a covenant or provision of the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security of each series affected.

Registered Global Securities and Book Entry System

The debt securities of a series may be issued in whole or in part in book-entry form and will be represented by one or more fully registered global securities.  We will deposit any registered global securities with a depositary or with a nominee for a depositary identified in the applicable prospectus supplement and registered in the name of such depositary or nominee.  In such case, we will issue one or more registered global securities denominated in an amount equal to the aggregate principal amount of all of the debt securities of the series to be issued and represented by such registered global security or securities.  This means that we will not issue certificates to each holder.

Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a registered global security may not be transferred except as a whole:

by the depositary for the registered global security to its nominee;

by a nominee of the depositary to the depositary or another nominee of the depositary; or

by the depositary for the registered global security to its nominee;
by a nominee of the depositary to the depositary or another nominee of the depositary; or
by the depositary or its nominee to a successor of the depositary or a nominee of the successor.

by the depositary or its nominee to a successor of the depositary or a nominee of the successor.

The prospectus supplement relating to a series of debt securities will describe the specific terms of the depositary arrangement involving any portion of the series represented by a registered global security.  We anticipate that the following provisions will apply to all depositary arrangements for debt securities:

ownership of beneficial interests in a registered global security will be limited to persons that have accounts with the depositary for such registered global security, these persons being referred to as “participants,” or persons that may hold interests through participants;

upon the issuance of a registered global security, the depositary for the registered global security will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the debt securities represented by the registered global security beneficially owned by the participants;

ownership of beneficial interests in a registered global security will be limited to persons that have accounts with the depositary for such registered global security, these persons being referred to as “participants,” or persons that may hold interests through participants;
upon the issuance of a registered global security, the depositary for the registered global security will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the debt securities represented by the registered global security beneficially owned by the participants;
any dealers, underwriters, or agents participating in the distribution of the debt securities will designate the accounts to be credited; and
ownership of beneficial interest in the registered global security will be shown on, and the transfer of the ownership interest will be effected only through, records maintained by the depositary for the registered global security for interests of participants, and on the records of participants for interests of persons holding through participants.

any dealers, underwriters, or agents participating in the distribution of the debt securities will designate the accounts to be credited; and


ownership of beneficial interest in the registered global security will be shown on, and the transfer of the ownership interest will be effected only through, records maintained by the depositary for the registered global security for interests of participants, and on the records of participants for interests of persons holding through participants.

10

The laws of some states may require that specified purchasers of securities take physical delivery of the securities in definitive form.  These laws may limit the ability of those persons to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary for a registered global security, or its nominee, is the registered owner of the registered global security, the depositary or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes under the indenture.  Except as stated below, owners of beneficial interests in a registered global security:

will not be entitled to have the debt securities represented by a registered global security registered in their names;

will not receive or be entitled to receive physical delivery of the debt securities in the definitive form; and

will not be entitled to have the debt securities represented by a registered global security registered in their names;
will not receive or be entitled to receive physical delivery of the debt securities in the definitive form; and
will not be considered the owners or holders of the debt securities under the relevant indenture.

will not be considered the owners or holders of the debt securities under the relevant indenture.

Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for the registered global security and, if the person is not a participant, on the procedures of a participant through which the person owns its interest, to exercise any rights of a holder under the indenture.

We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take the action, and the participants would authorize beneficial owners owning through the participants to give or take the action or would otherwise act upon the instructions of beneficial owners holding through them.

We will make payments of principal and premium, if any, and interest, if any, on debt securities represented by a registered global security registered in the name of a depositary or its nominee to the depositary or its nominee, as the case may be, as the registered owners of the registered global security.  Neither we nor the trustee, or any other agent of ours or the trustee will be responsible or liable for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

We expect that the depositary for any debt securities represented by a registered global security, upon receipt of any payments of principal and premium, if any, and interest, if any, in respect of the registered global security, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the registered global security as shown on the records of the depositary.  We also expect that standing customer instructions and customary practices will govern payments by participants to owners of beneficial interests in the registered global security held through the participants, as is now the case with the securities held for

the accounts of customers in bearer form or registered in “street name.”  We also expect that any of these payments will be the responsibility of the participants.

If the depositary for any debt securities represented by a registered global security is at any time unwilling or unable to continue as depositary or stops being a clearing agency registered under the Exchange Act, we will appoint an eligible successor depositary.  If we fail to appoint an eligible successor depositary within 90 days, we will issue the debt securities in definitive form in exchange for the registered global security.  In addition, we may at any time and in our sole discretion decide not to have any of the debt securities of a series represented by one or more registered global securities.  In that event, we will issue debt securities of the series in a definitive form in exchange for all of the registered global securities representing the debt securities.  The trustee will register any debt securities issued in definitive form in exchange for a registered global security in the name or names as the depositary, based upon instructions from its participants, shall instruct the trustee.

11

We may also issue bearer debt securities of a series in the form of one or more global securities, referred to as “bearer global securities.”  We will deposit these securities with a depositary identified in the prospectus supplement relating to the series.  The prospectus supplement relating to a series of debt securities represented by a bearer global security will describe the applicable terms and procedures.  These will include the specific terms of the depositary arrangement and any specific procedures for the issuance of debt securities in definitive form in exchange for a bearer global security, in proportion to the series represented by a bearer global security.

Concerning the Trustee

The indenture provides that there may be more than one trustee under the indenture, each for one or more series of debt securities.  If there are different trustees for different series of debt securities, each trustee will be a trustee of a trust under the indenture separate and apart from the trust administered by any other trustee under that indenture.  Except as otherwise indicated in this prospectus or any prospectus supplement, any action permitted to be taken by a trustee may be taken by such trustee only on the one or more series of debt securities for which it is the trustee under the indenture.  Any trustee under the indenture may resign or be removed from one or more series of debt securities.  All payments of principal of, and any premium and interest on, and all registration, transfer, exchange, authentication and delivery of, the debt securities of a series will be effected by the trustee for that series at an office designated by the trustee in New York, New York.

The indenture provides that, except during the continuance of an event of default, the trustee will perform only such duties as are specifically set forth in the indenture.  During the existence of an event of default, the trustee will exercise those rights and powers vested in it under the indenture and use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

If the trustee becomes a creditor of ours, the indenture places limitations on the right of the trustee to obtain payment of claims or to realize on property received in respect of any such claim as security or otherwise.  The trustee may engage in other transactions.  If it acquires any conflicting interest relating to any duties concerning the debt securities, however, it must eliminate the conflict or resign as trustee.

No Individual Liability of Incorporators, Stockholders, Officers or Directors

The indenture provides that no past, present or future director, officer, stockholder or employee of ours, any of our affiliates, or any successor corporation, in their capacity as such, shall have any individual liability for any of our obligations, covenants or agreements under the debt securities or the indenture.

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

The deposit agreement will contain terms applicable to the holders of depositary shares in addition to the terms stated in the depositary receipts.  Each owner of depositary shares will be entitled to all the rights and preferences of the preferred stock underlying the depositary shares in proportion to the applicable fractional interest

in the underlying shares of preferred stock.  The depositary will issue the depositary receipts to individuals purchasing the fractional interests in shares of the related preferred stock according to the terms of the offering described in a prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the entitled record holders of depositary shares in proportion to the number of depositary shares that the holder owns on the relevant record date.  The depositary will distribute only an amount that can be distributed without attributing to any holder of depositary shares a fraction of one cent.  The depositary will add the undistributed balance to and treat it as part of the next sum received by the depositary for distribution to holders of depositary shares.

13

If there is a non-cash distribution, the depositary will distribute property received by it to the entitled record holders of depositary shares, in proportion, insofar as possible, to the number of depositary shares owned by the holders, unless the depositary determines, after consultation with us, that it is not feasible to make such distribution.  If this occurs, the depositary may, with our approval, sell such property and distribute the net proceeds from the sale to the holders.  The deposit agreement also will contain provisions relating to how any subscription or similar rights that we may offer to holders of the preferred stock will be available to the holders of the depositary shares.

Conversion, Exchange, Redemption and Liquidation

If any series of preferred stock underlying the depositary shares may be converted or exchanged, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares represented by the depositary receipts.

The terms on which the depositary shares relating to the preferred stock of any series may be redeemed, and any amounts distributable upon our liquidation, dissolution or winding up, will be described in the relevant prospectus supplement.

Voting

When the depositary receives notice of a meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the particulars of the meeting to the record holders of the depositary shares.  Each record holder of depositary shares on the record date may instruct the depositary on how to vote the shares of preferred stock underlying the holder’s depositary shares.  The depositary will try, if practical, to vote the number of shares of preferred stock underlying the depositary shares according to the instructions.  We will agree to take all reasonable action requested by the depositary to enable it to vote as instructed.

Amendments

We and the depositary may agree to amend the deposit agreement and the depositary receipt evidencing the depositary shares.  Any amendment that (a) imposes or increases certain fees, taxes or other charges payable by the holders of the depositary shares as described in the deposit agreement or that (b) otherwise prejudices any substantial existing right of holders of depositary shares, will not take effect until 30 days after the depositary has mailed notice of the amendment to the record holders of depositary shares.  Any holder of depositary shares that continues to hold its shares at the end of the 30-day period will be deemed to have agreed to the amendment.

Termination

We may direct the depositary to terminate the deposit agreement by mailing a notice of termination to holders of depositary shares at least 30 days prior to termination.  In addition, a deposit agreement will automatically terminate if:

the depositary has redeemed all related outstanding depositary shares, or

we have liquidated, terminated or wound up our business and the depositary has distributed the preferred stock of the relevant series to the holders of the related depositary shares.

the depositary has redeemed all related outstanding depositary shares, or
we have liquidated, terminated or wound up our business and the depositary has distributed the preferred stock of the relevant series to the holders of the related depositary shares.

Payment of Fees and Expenses

We will pay all fees, charges and expenses of the depositary, including the initial deposit of the preferred stock and any redemption of the preferred stock.  Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges as are stated in the deposit agreement for their accounts.

14

Resignation and Removal of Depositary

At any time, the depositary may resign by delivering notice to us, and we may remove the depositary.  Resignations or removals will take effect upon the appointment of a successor depositary and its acceptance of the appointment.  The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50 million.

Reports

The depositary will forward to the holders of depositary shares all reports and communications from us that are delivered to the depositary and that we are required by law, the rules of an applicable securities exchange or our restated certificate of incorporation to furnish to the holders of the preferred stock.  Neither we nor the depositary will be liable if the depositary is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement.  The deposit agreement limits our obligations and the depositary’s obligations to performance in good faith of the duties stated in the deposit agreement.  Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding connected with any depositary shares or preferred stock unless the holders of depositary shares requesting us to do so furnish us with satisfactory indemnity.  In performing our obligations, we and the depositary may rely upon the written advice of our counsel or accountants, on any information that competent people provide to us and on documents that we believe are genuine.

We may sell the securities offered by this prospectus to one or more underwriters or dealers for public offering and sale by them or to investors directly or through agents.  The accompanying prospectus supplement will set forth the terms of the offering and the method of distribution and will identify any firms acting as underwriters, dealers or agents in connection with the offering, including:

the name or names of any underwriters, dealers or agents;
the purchase price of the securities and the proceeds to us from the sale;

any discounts or concessions allowed or reallowed or paid to dealers; and

any securities exchange or market on which the securities offered in the prospectus supplement may be listed.

Only those underwriters identified in such prospectus supplement are deemed to be underwriters in connection with the securities offered in the prospectus supplement.

The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at prices determined as the applicable prospectus supplement specifies.  The securities may be sold through a rights offering, forward contracts or similar arrangements.  In connection with the sale of the securities, underwriters, dealers or agents may be deemed to have received compensation from us in the form of underwriting discounts or commissions and also may receive commissions from securities purchasers for whom they may act as agent.  Underwriters may sell the securities to or through dealers, and the dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent.  Some of the underwriters, dealers or agents who participate in the securities distribution may engage in other transactions with, and perform other services for, us or our subsidiaries in the ordinary course of business.

We will provide in the applicable prospectus supplement information regarding any underwriting discounts or other compensation that we pay to underwriters or agents in connection with the securities offering, and any

discounts, concessions or commissions which underwriters allow to dealers.  Underwriters, dealers and agents participating in the securities distribution may be deemed to be underwriters, and any discounts and commissions they receive and any profit they realize on the resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act of 1933.  Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

The securities may or may not be listed on a national securities exchange.  In connection with an offering, the underwriters may purchase and sell securities in the open market.  These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales.  Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in an offering.  Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress.  The underwriters also may impose a penalty bid.  This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased securities sold by or for the account of that underwriter in stabilizing or short-covering transactions.  These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the securities.  As a result, the price of the securities may be higher than the price that otherwise might exist in the open market.  If these activities are commenced, they may be discontinued by the underwriters at any time.

Item 15.  Indemnification of Directors and Officers.

Opexa Therapeutics, Inc. (the “Company”) has the authority under Articles 2.02a(16) and 2.02-1Officers.

Section 8.101 of the Texas Business Corporation Act (“TBCA”Corporations Law (the “TCA”) authorizes the Registrant to indemnify its directors and officers to the extent provided for in such statute. The TBCA provides, in part, that a corporation may indemnify a director or officer or othercertain persons, including any person who was, is or is threatened to be made a named defendant or respondent in a threatened, pending or completed action or other proceeding, because suchthe person is or was a director officer, employee or agent of the corporation, if it is determined that such person: (1) conducted himself in good faith; (2) reasonably believed, in the case of conduct in his official capacity as a director or officer, of the corporation, that his conduct was in the corporation’s best interest and, in all other cases, that his conduct was at least not opposed to the corporation’s best interests; and (3) in the case of any criminal proceeding, had no reasonable cause to believe that his conduct was unlawful.

A corporation may indemnify a person under the TBCA against judgments penalties, including excise and similar taxes, fines, settlement, unreasonable expenses actually incurred by the person in connection with the proceeding. If the person is found liable to the corporation or is found liable on the basis that personal benefit was improperly received by the person, the indemnification is limited to reasonable expenses actually incurred by the person in connection with the proceeding, and shall not be madethreatened, pending or completed action or other proceeding.  The Registrant is required by Section 8.051 of the TCA to indemnify a director or officer against reasonable expenses actually incurred by him or her in respect of anyconnection with a threatened, pending, or completed action or other proceeding in which the person shall have been found liable for willfulhe or intentional misconduct in the performance of his duty to the corporation. The corporation may also pay or reimburse expenses incurred by a person in connection with his appearance as a witness or other participation in a proceeding at a time when heshe is not a named defendant or respondent because he or she is or was a director or officer if he or she has been wholly successful, on the merits or otherwise, in the defense of the action or proceeding.

The Company’s amended andRegistrant’s restated articlescertificate of incorporation provideformation provides that none of its directors shall be personally liable to the CompanyRegistrant or its shareholders for monetary damages for an act or omission in such director’s capacity as a director; provided, however, that the liability of such director is not limited to the extent that such director is found liable for (i) a breach of the director’s duty of loyalty to the CompanyRegistrant or its shareholders, (ii) an act or omission not in good faith that constitutes a breach of duty of the director to the CompanyRegistrant or an act or omission that involves intentional misconduct or a knowing violation of the law, (iii) a transaction from which the director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director’s office, or (iv) an act or omission for which the liability of the director is expressly provided by an applicable statute.

The Company believes that these provisions will assist it in attracting and retaining qualified individuals to serve as executive officers and directors. The inclusionRegistrant’s restated certificate of these provisions in the Company’s amended and restated articles of incorporation may have the effect of reducing the likelihood of derivative litigation against the Company’s directors and may discourage or deter shareholders or management from bringing a lawsuit against

directors for breach of their duty of care, even though such an action, if successful, might otherwise have benefited us or our shareholders.

The Company’s amended and restated articles of incorporationformation and amended and restated bylaws provide that the Company mayRegistrant shall indemnify its officers, directors, agents and any other persons to the fullest extent permitted by the TBCA.

Additionally, underapplicable law.  The Registrant’s directors and officers are covered by insurance indemnifying them against certain liabilities which might be incurred by them in their capacities as such.  Pursuant to terms of their employment agreements withcontracts, certain of the Company, Mr. Warma and Ms. RillRegistrant’s officers are entitled to indemnification in their capacity as officers of the Companysuch and to the fullest extent permitted by the TBCA.

(B)           Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.  As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.  Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)           That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

II-2

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)          Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)         Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)        The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)        Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6)           To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act (the “Act”) in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.

(7)           That, for the purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initialbona fideoffering thereof.

(8) With respect to any offering in which securities are to be offered to existing security holders pursuant to warrants or rights and any securities not taken by security holders are to be reoffered to the public, the Registrant hereby undertakes to supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

II-3


Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to any charter provision, by law or otherwise, the registrant has been advised that in the opinion of the SECSecurities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
